问题
I am just getting my feet wet with MVC 6. I installed VS 2015 and with the default ASP.NET 5 preview MVC Web Application template everything runs fine under local IIS.
I then tried to switch out the Default DI container with StructureMap following these instructions exactly (note it is a very recent article). The only thing is I had to figure out the namespaces to import myself (since the author neglected to include them) and this is what I included.
I put the StructureMapRegistration class and all related classes into a single file, and here are the usings.
using Microsoft.Framework.DependencyInjection;
using StructureMap;
using StructureMap.Configuration.DSL.Expressions;
I added the following usings to the Startup.cs file.
using StructureMap;
using StructureMap.Graph;
using System.Reflection;
And I made the following edit to the Startup.cs file.
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// Add Entity Framework services to the services container.
services.AddEntityFramework()
.AddSqlServer()
.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]));
// Add Identity services to the services container.
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
// Configure the options for the authentication middleware.
// You can add options for Google, Twitter and other middleware as shown below.
// For more information see http://go.microsoft.com/fwlink/?LinkID=532715
services.Configure<FacebookAuthenticationOptions>(options =>
{
options.AppId = Configuration["Authentication:Facebook:AppId"];
options.AppSecret = Configuration["Authentication:Facebook:AppSecret"];
});
services.Configure<MicrosoftAccountAuthenticationOptions>(options =>
{
options.ClientId = Configuration["Authentication:MicrosoftAccount:ClientId"];
options.ClientSecret = Configuration["Authentication:MicrosoftAccount:ClientSecret"];
});
// Add MVC services to the services container.
services.AddMvc();
//// Uncomment the following line to add Web API services which makes it easier to port Web API 2 controllers.
//// You will also need to add the Microsoft.AspNet.Mvc.WebApiCompatShim package to the 'dependencies' section of project.json.
//// services.AddWebApiConventions();
//// Register application services.
//services.AddTransient<IEmailSender, AuthMessageSender>();
//services.AddTransient<ISmsSender, AuthMessageSender>();
var container = new Container();
container.Configure(x =>
{
x.Scan(scanning =>
{
scanning.Assembly(Assembly.GetExecutingAssembly());
scanning.TheCallingAssembly();
scanning.WithDefaultConventions();
});
//x.AddRegistry<WebsiteRegistry>();
});
// Our framework extension point
container.Populate(services);
}
Literally, the only things I have changed from the default template are the above code changes and installing
StructureMap3.1.6.186.
The using statements suppress all of the design time compilation errors, but when I build, I get several other errors.

The error indicates where the problem is - I need a reference to mscorlib 2.0.5.0. But I am already referencing mscorlib 4.0.0.0 in the project.
At this point in ASP.NET < 5, the next step would typically be to add some binding redirects to the <bindingRedirect> section of the web.config file. However, after searching for how to do this in ASP.NET 5, I came across this answer which indicates that binding redirection is supposed to be "totally automatic".
So is this a bug, or is there some step in my configuration that I missed that is resulting in this error?

回答1:
Thanks to opiants, the problem appears to be related to the fact that the dnxcore50 framework was included in the project.
"frameworks": {
"dnx451": { },
"dnxcore50": { }
}
Removing it solved the issue.
"frameworks": {
"dnx451": { }
}
